AbstractAs highly sensitive and specific markers of myocardial damage, cardiac troponins were demonstrated to correlate with clinical parameters of patients with hypertrophic cardiomyopathy. However, the relationship between cardiac troponins and presence of non-sustained ventricular tachycardia (NSVT) in hypertrophic cardiomyopathy remains unclear. The aim of our study was to explore the association between serum cardiac troponin I (cTNI) and presence of NSVT in patients with hypertrophic obstructive cardiomyopathy (HOCM). A total of 309 HOCM patients were enrolled in our study. All participants underwent clinical evaluat...

Non-cardiac surgery for hypertrophic obstructive cardiomyopathy (HOCM) is considered to require meticulous perioperative care. β-blockers are considered the first-line drugs for patients with HOCM, and they pl...

ConclusionsSeptal myectomy, performed in a tertiary referral center, had a 30-day mortality rate of 0% and low morbidity rate. There was no difference between observed myectomy mortality and STS Calculator predicted risk for AVR and MV repair. It is possible that a larger sample could reveal lower mortality than STS prediction.

"Incompatible Housemates": Hypertrophic Obstructive Cardiomyopathy and Takotsubo Syndrome. Intern Med. 2019 Dec 06;: Authors: Sato Y, Matsumoto K, Sakai J, Nakamura T, Tanaka H, Hirata K Abstract This case report concerns an 81-year-old woman with previously well-controlled hypertrophic obstructive cardiomyopathy (HOCM). She was referred to our hospital because of the acute onset of takotsubo syndrome. Echocardiography revealed basal hyperkinesis due to takotsubo syndrome superimposed on septal hypertrophy, which resulted in the reappearance of prominent left ventricular outflow tract obstruc...

ConclusionsIn our cohort of children with hypertrophic obstructive cardiomyopathy undergoing septal myectomy, biventricular obstruction, myocardial bridging, and intraventricular anatomical abnormalities are frequent phenotypic components. Despite the complexity of childhood hypertrophic obstructive cardiomyopathy, surgical treatment results in a favorable outcome in carefully selected patients.

LVOT gradient in HOCM – Doppler echocardiogram Left ventricular outflow tract gradient in hypertrophic obstructive cardiomyopathy Left ventricular outflow tract gradient (LVOT) in hypertrophic obstructive cardiomyopathy (HOCM) is usually  measured from the apical five chamber view (apical 5C) in echocardiography. Initially the apical 5C view is obtained and then the colour Doppler flow mapping (CFM) is done to locate the flow in LVOT. Continuous wave (CW) Doppler cursor is then aligned along the LVOT colour jet of HOCM. The CW jet in HOCM is described as dagger shaped or sickle shaped, unlike the symmetrical ton...

Abstract AimsPercutaneous septal reduction therapy by either alcohol or nonalcohol agents is an alternative approach to surgery in drug‐refractory symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM). Nonalcohol agents have some advantages and disadvantages over alcohol during the procedure. Nowadays, a novel non‐alcohol agent, named as Ethylene‐vinyl alcohol (EVOH) copolymer (Onyx® and Squid®), is used during septal ablation. Thus, in this study, we aimed to evaluate both acute and long‐term efficacy and safety profile of EVOH during septal ablation in HOCM. Methods and resultsA total o...
